CodeMCP vs fastapi_mcp
CodeMCP: CKB transforms your codebase into a queryable knowledge base, enabling semantic search, impact analysis, dead code detection, ownership lookup, and more through CLI, API, or AI assistants. It reduces AI tool calls by 60-70% with compound operations and integrates seamlessly with MCP-compatible tools.; fastapi_mcp: FastAPI-MCP allows you to expose your existing FastAPI endpoints as Model Context Protocol (MCP) tools. It offers native integration with FastAPI, including built-in authentication using existing dependencies, and preserves schemas and documentation.

When to choose:
- You already have a FastAPI application and want to expose its endpoints as MCP tools while reusing your existing FastAPI authentication dependencies and Swagger schemas.
- You want to mount the MCP server directly onto your ASGI app or deploy it separately under an MIT license.
When to skip:
- You are building a standalone MCP server from scratch rather than wrapping a FastAPI app; use FastMCP or the official MCP Python SDK.
- You need an actively updated repository (last push was November 2025).
